Information on changes as published. Pete Richards The CSCC Special Saloons and Modsports rules and regulations have gone broadly unchanged since 2012. Many of the original pre-1994 cars and drivers have joined us, together with new cars built to these regulations. The cars remain a crowd favourite,...

Bit of an old thread but the CSSC have announced that bike engines will be allowed for Imps in 2020 with a new class structure.

Worth checking the manifold for obstructions. I cut up a log type 28/36 manifold several years ago to turn into manifold for bike carbs and found the 'logs' to be partially obstructed by casting flashings.

Pete Richards

Video of the races has just appeared on the SMRC web site. Does not show the incident but does show the result. Also shows the restarted race and the second race.

So that must be more than 50p in the pot!

Glad to hear that you are ok and the car not too bad.

Thanks Simon.

I had to pay twice as both the car and driver had to be recovered!

Pete Richards

Having had a week to take it all in I thinks it's time to spill the beans. We arrived at a very wet Knockhill on Friday evening. Found the correct paddock and had a quick look round. After some food we noted that the rain appeared to be horizontal and as the motorhome heating was not working it was ...

No takers - I assume everyone's going to Bo'ness.

If anyone should decide to come along make yourself known and I'm sure we can supply tea/coffee.

Pete Richards

All sorted. Entry accepted and tickets arrived today. On the ticket front I have 3 going spare so should anyone be interested in attending get in touch. I should be able to get them posted so they arrive before the meeting. Alternatively I can arrange for them to be left at the gate if that's an acc...

I'm in the process of sorting an entry for the Scottish Classic Sports and Saloons race at this event. I intend combining it with a short break and I'm asking if anyone north of the border has any contacts with the circuit who would be able to arrange safe storage for my Clan and trailer there after...

Not had the selector shaft problem but did do the zip on my race suits at the Top Gear Show at Silverstone many years ago. Luckily at that time I got my race suits from Jaybrand at Peterborough and it was just a trip on Monday to get a new one fitted. I don't expect any of the suppliers provide that...

Scott,

I'll have a look to get where it was happening but may take a couple of days as I've got a Newsletter to do for the local motor club.

Pete Richards

Interesting to watch. I can't remember but do you have an LSD/Quaife diff fitted? If so it looks to me that you are not taking full advantage off it, particularly on the right where you were changing down, I'm guessing into 1st mid corner, and suffering understeer. Keeping in the higher gear and and...

I did use a 100% Ethylene Glycol as coolant in my original Clan as I was having problems with boiling when I started racing. With it's higher boiling point it did work. However, when the hose failed to the heater as I finished practice at Lydden Hill I can confirm that the drenching of my feet with ...

Scott, I hope you can sort the problem with third gear with a simple gear lever move. Having experienced the same problem many times as you describe, unfortunately it usually turned out to be a gearbox rebuild being required. The only time I've driven at Knockhill, the Imp track evening, I had to ho...

Pete Helical CR with Quaife diff, why ? Scott Scott, I guessed you had a Quaife diff but wasn't sure of the ratios. With the helical CR is that using the old rally ratios of a raised first and lowered third? I couldn't be sure what gear you were in approaching the hairpin. It looked to me, and I'm ...

Must get to Knockhill this year if I can. Perhaps do a round of the Scottish Sports and Saloons Series and combine it with a holiday.

What gearbox are you using?

Pete Richards

As has been said I've used mixed standard buckets with no problems. I do, however, chamfer the leading edge as recommended by Andy Dawson.

Pete Richards

Moose,

Think it's the pictures. I believe the marks on the pistons are from the fragments of piston before, in the case of No2 they left via the exhaust.

Peter,

Deves rings were fitted.

Pictures showing damage.

Pete Richards

Scott, what make were the pistons you were using. I ask as I have just suffered what appears to be the same problem. In my case I had tested my orange Clan at Blyton Park and whilst it appeared run OK there was pressurisation of the cooling system resulting in water being dumped. The interesting thi...

Tim,

Hope it's smoother than it was when I was there in 1986!

Pete Richards

Still great fun and lucky to have such a great venue.

Many years of Autocross taught me that the green stuff is not great for braking

Pete Richards

Looks like a great club event but to me it appeared to me with no reversing more like an autosolo! By the way, what's the green stuff?

Pete Richards

I have discs, front and rear, on one of my racing Clans using X1/9 bits. My original racing Clan has discs on the front, Vauxhall Viva, and Imp drums on the rear. To be honest I don't think there is anything to gain from the rear discs, particularly with the work involved. With rear drums the main t...

I'm using Lada split m/c in my latest BMW powered Clan but it did need some modification to fit the Imp pedal box. It does fit beneath a standard Clan fuel tank (Imp with modified filler neck).

I've since been told that a non servo m/c from a Ford Escort Mk 3 fits and works well.

Pete Richards

Another event that may be of interest is the Classic & Modern Motorsport Festival at Mallory Park on June 11th. This has a Invitation British T'bred/Classic Challenge with a potential second race being the end of meeting Sports carV Saloon car Challenge. Further details at www.cmmotorsportclub.com P...

I'm assuming that the attachment is for the final result and from your comments you are obviously more than pleased with it. However, based on the information provided I am of the opinion that the result obtained is not taking full advantage of the characteristics of the Fraser B cam. In this contex...

Couple of pictures from Banbury yesterday.

Pete Richards

It's right the the crossmember forms part of the chassis for the G15. As has been said none of the normal methods of adding strength are appropriate. Also, it's necessary to remove the body to check out the integrity of the complete chassis, particularly the welds. On two occasions I found that not ...

Steve, That was for the Special Saloon/Modsports Series. I detected a softening of the attitude due to the specifications of the 'New' cars that appeared this year being in my opinion modern interpretations of the original regulations but using combinations of chassis and engine that did not appear ...

Could be worth you speaking direct to the CSCC again as I spoke to Hugo earlier this year about competing in my Clan with a BMW engine and he was only concerned about the year of the ECU. I was talking about the K1100 and that was just within the cutoff date of I believe 1991 so the K100 should be O...

I'm currently running one of my Clans with a R22 cam and twin Weber 40's using an Accuspark programmable ignition module and a locked 25D distributor. The results are very good but I had to make sure that I had the software that goes to 10,000 rpm. It's a basic 2D system that allows you to set the i...

Well done to Steve and thanks to Simon for the help with the alternator bracket. Unfortunately the belt was shredded again but not until after being attacked by a Spitfire. Despite the very loud impact damage restricted to tyre marks and slight paint removal - don't know about the Spitfire. Strong c...

In my opinion the clutch plate should work OK. Whilst stripped down check everything - by measurement not just by eye. Have you checked that the pressure plate is flat and not concave - because it was in the correct box does not mean that it was perfect. The roller bearing is heavier than the carbon...

The roller bearing may be the same thickness but how about the fixing lugs? Are they in the same position? Where they slot into the arm may also be distorted over time.

Pete Richards

I've just read a bit more and note that the change down the box is the main problem but is better if you double declutch. From that I'd say that the clutch is not fully engaging with the cause being probably related to the roller release bearing being too thick. I know it's a faff removing the engin...

Worth checking that the arm is not bent.

Pete Richards

I've always towed the Clan with it being put on forwards. My trailer is just like yours and I find it to be very stable and I've been towing like that for more years than I care to remember, both in the UK and on the Continent. I reckon the tyre rack balances things out nicely, particularly when the...

Best of luck Frank and as Simon says enjoy yourself.

Pete Richards

Check the master switch, They appear to be short lived and rubbish these days. Had an electrical fault related to starting on my original race Clan for at least a year. Finally cured by replacing the master switch.
